1 in 3 US adults aged 40-59 years has high blood pressure (hypertension); among those over 60 years of age the prevalence is over two-thirds, 67%. High blood pressure is a well known risk factor for cardiovascular disease; the leading cause of death worldwide.[1, 2] As two-thirds of sudden cardiac deaths occur in clinically healthy individuals , novel indicators of early recognition of adverse cardiometabolic risk in disease-free adults are clearly needed. It has been demonstrated that healthy disease-free adults with high-normal blood pressure (aka pre-hypertension, defined as 120-139/80-89 mmHg) have an adverse cardiometabolic risk profile.
The prevalence of high-normal blood pressure in disease-free US adults is 36.3%; it is especially common in people with overweight/obesity, enlarged waist lines, and elevated glucose, insulin, hemoglobin A1c (glycated glucose), C-reactive protein (an inflammatory marker), and triglycerides (blood fats).
High-normal blood pressure is an independent risk factor for cardiovascular disease (CVD)...[3-5]
It is well-documented that testosterone levels decline with age in men.
After the age of 40 years, total testosterone decreases on average -4 ng/dL ( -0.124 nmol/L) per year  or 1.6% per year , and bioavailable testosterone by -2 to 3% per year. 
In older men (over 60 years of age), the average rate of decrement in total testosterone levels has been found to be 110 ng/dL every decade.
However, the relative contributions of changes in health and lifestyle to that decline have not been adequately evaluated. A notable study was set out to investigate this...
The objective of this study was to establish the relative importance of aging, health, and lifestyle in contributing to the testosterone decline in aging men.
